Experimental investigation on new steerable dielectric resonator antenna

A new steerable-dielectric resonator antenna is described. It consists of a movable annulus of heterogeneous dielectric sections surrounding a cylindrical core of another dielectric. The antenna far-field radiation was found to be manipulated by changing the angular position of this ring. This antenna demonstrates resonance at ~1.2 GHz with a fractional bandwidth of 28.3% (Sn₁₁< - 10 dB), confirming an HFSS simulation of the same structure.
